A Bird Story is an hour-long adventure game about a boy who finds an injured bird. It takes place between memories and dreams, telling a simple and surreal tale without dialog.

The game is set in the universe of To the Moon and acts as a bridge between Episode 1 and Episode 2 of the series, as the boy grows up to be the elderly patient in Episode 2. However, the game is made to be self-contained with its own beginning and ending.
